Hi Serge, At first, yes, I was trying with VirtIO.
Later, I disabled VirtIO for Disk, didn't solve. Then, I disabled VirtIO for Net, didn't solve. Again, I disabled VirtIO for both Disk and Net, didn't solve. But, thinking on it again now, I did not tested it with a Windows 2008 R2 that did not touched VirtIO drivers, I mean, in all of my tests, I was using at least, the ballon RAM driver (and probable VirtIO Serial, or something like that). Next week, I'll try it with again, without any VirtIO, from the beginning, with KSM=1.
